Bug-fixing comments are comments posted in a discussion thread attached to a bug report. Typically, they provide bug-fixing clues such as: resolution instructions, inline links to related bug reports, commit links, patch links, and positive affirmation when a bug report has been fixed [1]}, [2]}, [3]}. Examples of such clues are observed in the comments depicted in Figure REF . Some of these comments may include insightful details and display positive language used by the person providing a bug-fixing comment. In general, these bug-fixing comments can be found from previously fixed bugs.
